foliaceous, but are much weaker than on the flattened part below 

 the beaks. 



Dimensions. — Length = 52 mm. ; height=45 mm.; diameter 

 of both valves = 27 mm. 



Locality. — Totara Point, Kawhia. 



Remarks. — This shell agrees closely in outline and ornamen- 

 tation with A. spitiensis (especially Holdhaus, pi. c, fig. 4 a), and 

 I have scarcely any doubt that it is specifically identical.

 Pal. Ind. ser. 15, vol. iv, pt. ii, fasc. 4, p. 443 & pi. xcix, figs. 12, 

 13, 15, pi. c, fig. 1. 



Description. — This shell agrees in general features with that 

 just described, but is smaller and has been apparently more elon- 

 gate ; the surface is more rounded, and the portion below and 

 adjacent to the beaks is less flattened. The hinge-margin pos- 

 terior to the beaks seems rather more curved. The surface is 

 covered with somewhat prominent irregularly-spaced growth-lines, 

 which vary in strength. 



Dimensions. — Length=46 mm. ; height=35 mm. ; diameter 

 = 25 mm. 



Locality. — Totara Point, Kawhia. 



Remarks. — This specimen seems to approach nearest to the 

 species of Holdhaus, especially the specimen that he figures in 

 pi. xcix, fig. 15 a. It may also be compared with a specimen of 

 jistarte hermanni Oppel in the same plate, fig. II a.

1913. 'Fauna of the Spiti Shales (Lamellibranchiata & Gasteropoda)' 

 op. cit. p. 444 & pi. c, figs. 2-3. 



Description. — Shell elongated, surface gently rounded; the 

 part below the beaks is hardly perceptibly flattened, but bears 

 widely spaced and regular growth-lines. On the remaining 

 surface of the shell the growth-lines are prominent, closely set, 

 and irregular in strength. 



Dimensions. — The specimen under description is much broken, 

 but has been about 57 mm. long, 40 mm. high, and 24 mm. in 

 diameter across the two valves. 



Locality. — Totara Point, Kawhia. 



Remarks. — This specimen, or what remains of it, closely 

 recalls that figured by Dr. K. Holdhaus, pi. c, fig. 2 a.

 &5.) 



Description. — Shell thick; beaks prominent, pointed, taper- 

 ing, close together, enclosing below them a deep, heart-shaped, 

 lunular depression. A rather prominent, angular, blunt ridge 

 commences behind the beak, and passes with a gentle curve to
